. Application filed July 20, 1922. Serial 110 576360.

The present invention relates to a demountable steel or iron tire adapted to cooperate with an ordinary railway or traction rail and to a telly to which the same is de mountably secured, the same being adapted to likewise receive, carry and cooperate with a demountable rim equipped with a solid rubber or pneumatic tire. This structure is Sl'lOWI'l in combination with a resilient wheel which is particularly adapted for use in this connection on account 01' its resiliency being well adapted for use either with a pneumatic tire, a solid tire or a. steel tire Cooperating with a tract-ion rail as aforesaid.

It'is the object of the invention not only to provide an elasticwheel ior use on street cars and railway coaches, but to provide a wheel T01. busses and similar vehicles which makes the vehicle convertible traveling either on pavement when equipped with pneumatic or solid rubber tires or on the rails when it is equipped with steel tires, the deinountable feature making it'convenient andiit'easible to change on short notice from one'to the other, so that the vehicle 1112143 10 advantage run part or" its route on the rails and part of its route on the pavement changing tires for this purpose intermediately of the run without considerable loss of time. In the accompanying drawing, I haveillustrated a wheel, telly and tire, embodying the features of my invention in the preferred form. In the drawings,

Figure 1 is a side elevation of an elastic wheel constructed in accordance with my invention, the wheel being shown fragmentarily for convenience of illustration.

Fig.2,is a section 011 the line 2-2 of Figure 1 taken at right angles to the plane of Figure 1. A n

Fig. 3, is a section corresponding to Fig. 1, through a difierent type of tire and rim.

Referring to the drawin s by numerals the wheel illustrated incluc es. an inner or hub portion 1, encircled by an outer-annular section '2, referred to for convenience as a spoke section, this is spaced from the outer section to provide radial play, the space between the sections being occupied by an annular resilient pad 3, which takes up the play between the sections and supplies resiliency to the structure. The outer or spoke section 2, as shown includes an inner rim' i, having spoke sockets 5, in .whichrwooden spokes are fitted and from which they exbears against the wedge ring 20.

tend outward radially. At the outer ends these spokes are secured to a channel like telly 7, which as it provides seating'and. securing means for the tire may also be refer-red to as a rim. As shown the spokes are provided at their outer ends with caps or bands S), which bear against the inner surface of the telly and the spokes are secured to the telly by means of lag screws 11, driven inward toward the center 01 the wheel from the outside of the rim through suitable apertures 12,:1nd extending into each spoke on the line of the axis. 1

The telly '7, as shown isof channel shape, the'bott'om 1 1, of the channel being nearest the center of the wheel,'the side walls15 and 16, being nkeierably oppositely. inclined so that they converge toward the center of the wheel and diverge toward the periphery. The leithand or outside'wall 15, has a hooked outer peripl'ieral edge 18, to receive the tire bead or edge of the. rim depending on the type of the or rim used and the other side wall has an inclined edge surface 19,to receive a wedgelocking ring 20, which enters between the tire or rim 21, and the edge of the rim. The locking ring 20, is held in position by lugs 22, placed at intervals along the inside of the telly, these lugs as shown have a foot 2a, which bears on an offset supporting surface '25, which as shown is punched out of the rim for this purpose at the edge 01 the bottom wall 14. The lug has an inner inclined face 26, which overlies the side wall of the rim, and at its upper edge At its extreme upper end the lug is formed into a hook 27, which takes. over the edge or bead 29, of the tire or rim, holding the latter in position on the telly.

The lugs are in turn held in position by bolts 30, one passing through each lug and through the telly from side to side parallel to the axis. The nuts 31, are for c0nvenience preferably brazed in position, and the bolts are passed trom the outside inward, that is, they are entered through the lugs.

The tire or rim 21, as shownis a circular steel band having a fiatperipheral surface 34, and an edge flange 35, the tire or rim being further provided with projecting edges or beads 29,10 be engaged by book 18, on. the telly on oneside and the hooks 27, on the lugson the other side. An im portant advantage of the invention is that the mere change of denrountable rims, no

more difiicult than the ordinary change oi rims incident to the operation of an automobile. The use of a dcmountable tire carrying rim in connection with a similar lelly is shown in Fig.3, oi the present application, in which a demountable rim -10, is sccured to the telly 7, similar to the lielly in Fig. 2, and in exactly the same way, the rim -10, in the present instance having beads $1 and 42, engaged by a hooked edge 18, and the lug hooks 22, and in the form of the invention shown, the rim carries a solid tire 43, though the rim construction is subject to considerable variation within the scope of the invention and either solid or pnemnatic may be used and the flanged tire maybe secured to any form of wheel in place of a rim having similar heads.

I have thus described specifically and in detail a'sin'gle embodiment of my invention inrorder that the nature and operation of same may be clearly understood, however, the specific terms herein are used descriptively rather than in a limiting sense, the

scope of the invention being defined in the claims.

What I claim and desire to secure by said Letters Patent is:

1. The combination of a hard tire having an ed e flange projectin outward radially there Tom, a projecting cad at each inner peripheral edge, a telly having a hooked flange at one side engaging the corresponding bead and hooked lugs at the other side engaging the other head.

2. In combination with a vehicle wheel, a

hard tire having a tread and an edge flange projecting outwardly radially therefrom beyond the tread, a bead n'ojccting from the inner periphery of said tire at each side and a telly having a hook integral therewith at one side for engaging one said bead and removable hooked lugs at the other side engaging the other head from the opposite side.

3. A hard tire having an outwardly projecting flange extending radially beyond the tread, a bead extending along the inner edgiat eachside a stationary hooked member on the wheel engaging said head at one side, an inclined face on the wheel opposite the other bead, a wedge ring engaging the inclined face and the rim at the other side and lugs for holding the wedge ring in place.

Signed by me at Baltimore, ll'laryland, this 17th day of July, 1922.
